I have the same problem when adding books.
Calibre hangs out, and I have to force close it.
I've noticed that not all books cause that, only some. I can provide a file with a book that always does that, but I don't want to post it here. I can do that if there is a way to share it privately.
If I open a book that does this with the Calibre ebook editor, I can see that Calibre has added the following:
Code:
<meta name="calibre:user_metadata:#sortedauthor" content="{"is_csp": false, "is_multiple2": {}, "is_multiple": null, "is_editable": true, "search_terms": ["#sortedauthor"], "link_column": "value", "datatype": "composite", "column": "value", "rec_index": 43, "#extra#": null, "colnum": 23, "name": "Sorted Author by LN, FN", "kind": "field", "category_sort": "value", "is_custom": true, "is_category": false, "table": "custom_column_23", "#value#": "Shupert, Derek", "label": "sortedauthor", "display": {"composite_template": "{author_sort}", "make_category": false, "use_decorations": 0, "contains_html": false, "composite_sort": "text"}}"/>
multiple times. Sometimes hundreds of times. With the books that don't hang, this code is missing.
Please, help.
